Some of the videos I watched suggested soaking the stone for 12-15 minutes prior to use. One suggested using vegetable oil on the surface versus water/soaking (I used water and presoaking it for 15-minutes). So instead of a simple 'out-of-the-box-and-use' approach, it required a bit of research before sharpening a knife. Otherwise I would have given this product a 5-star rating.
The Work Sharp WSKTS-KO Knife and Tool Sharpener is a handheld device, which is optimized to handle various sharpening jobs. It comes with a belt sander, which spins around following a triangular configuration. It has a set of angles on either side, which can be adjusted from 15 to 30 degrees, depending on your sharpening needs. Unlike other electric knife sharpeners, which tend to overheat during high speeds, the speed of this one is adjustable.
The truth is that there is no one recommendation that we can make that will meet everyone’s needs. Every sharpener’s needs are different and every sharpening toolkit will be different. In order to help beginning sharpeners get started with good sharpening stones to build around, we need to understand their individual needs. So with that in mind, let’s look at the basic needs of a beginning sharpener.
Oilstones, like the Norton whetstone, can be made out of natural or synthetic material like Novaculite, Aluminium Oxide, or Silicon Carbide. As per the name, oilstones require the use of oil as you sharpen your knife's blade. This type of stone is slower at sharpening or honing a blade and it can be messy and you need to always have some oil on hand but it creates a nice sharp edge and a beautiful polish.
I bought this knife sharpener for my son as a Christmas present years ago and recently (but cautiously) used it on my cutlery (Henkel and Wusthof). Frankly, I had been a little lazy and let my knifes lose a bit of their edge. I did not feel like getting out my stones and oil to do a proper job, so I borrowed my son's sharpener. It really works great, which I hate to admit, as it feels like a cheat and it is a fraction of what I spent on stones. I realize that I need to buy one for myself, so I looked around to see if there is anything better and I could not see anything that looked better. This one is adjustable, which is what I need. I looked at the 1 star ratings and there was a common theme that the knife edge chatters as the blade is pulled across. It can, if you don't use it properly! If your blade is very dull, you will need to pull with a very light, steady, and quick motion. You never need to push down hard as you pull. Even pressure. Don't be a brute! Finesse is what is needed. I am going to buy another one for me.
The Fallkniven DC3 Diamond/Ceramic Whetstone Sharpener will make a believer out of anyone willing to invest a bit of time in the process. A big advantage of this stone is that it can be taken anywhere, used anywhere, without any form of lubrication and will produce an amazing sharp edge on whatever needs sharpening. Timeless Old World tech that still dazzles.

Most professional knife makers mainly use flexible belts, when putting a razor sharp edge on the blades. You can now use the same technology at home to sharpen your knives, every time they become dull. You might have other sharpening tools and methods at home. However, it is quite hard to find one that does the job better and faster than the Work Sharp WSKTS-KT Knife sharpener.
The knives sharpening system is multifunctional. It has three slots for ceramic knives, dull metal knives and a slot for finishing and polishing the edges. It is very safe to use. Hence, no need to worry about accidents or to damage your blades in the process of sharpening. The base is non-slip in nature due to the heavy duty non-slip rubber used. This provides extra grip thus boosting its safety. The main body is light and yet durable at the same time.

As opposed to water whetstones that require you to pre-soak the stone, the Norton oil stone is pre-filled with oil to save time and eliminate the need to pre-soak it prior to use and the lubricant stays on the surface during sharpening.  The oil also prevents metal from bonding with the abrasive surface by flushing away dislodged abrasive and metal chips.
An extremely well written and informative article on sharpening. Overtime we all get to love certain stones for our sharpening needs. I am a huge coticule fan, and although i have used all the others, i always come back to this natural stone above all others. Still trying to figure if i chose it or it chose me! NEver the less there are so many options out there it is not hard with a little time and effort to find the right combination for your needs.
When the stone is intended for use on a flat surface, it is called a Bench Stone. On the other hand, small, portable, hand-held stones are referred to as Pocket Stones. Also, because Pocket Stones are smaller than Bench Stones, they are more easily transported but, they also present difficulty in maintaining a consistent angle and even pressure when attempting to sharpen longer blades. Consequently, Bench Stones are commonly used at home or in camp whereas, Pocket Stones are generally reserved for honing an edge in the field.
It's okay, but wish I purchased a different stone. The stone is too soft, therefore knife slowly cuts away the stone causing it to be unlevel. I am completely unable to keep it level, thus for me the stone became worthless. Feel the stone is cheaply made; I'd suggest buying a slightly more expensive whetstone. At end I had to trashed this stone and buy a new stone.
Clamp-style sharpening tools use a clamp with several holes with predefined angles. The stone is mounted on a rod and is pulled through these holes, so that the angle remains consistent. Another system is the crock stick setup, where two sticks are put into a plastic or wooden base to form a V shape. When the knife is pulled up the V, the angle is held so long as the blade is held perpendicular to the base. Several cutlery manufacturers now offer electric knife sharpeners with multiple stages with at least one grinding stage. These electric sharpeners are typically used in the kitchen but have the ability to sharpen blades such as pocket or tactical knives. The main benefit of using an electric sharpener is speed with many models that can complete the sharpening process in one to two minutes. The disadvantage is that the sharpening angle is fixed so some specialized knives, like a Japanese style Santoku, may need additional attention to sharpen to the ideal angle.

Therefore, the first step to choosing a whetstone is to determine your intended purpose and then choose your whetstone accordingly. For instance, when sharpening tools that do not require a fine edge, you should choose a relatively soft, coarse, stone such as a Norton Crystolon water stone. However, for sharpening tools that do require a fine edge, a somewhat harder Norton India oil stone would be a good choice. But, for sharpening hunting knives where an exceptionally fine edge is required, a Novaculite or Coticule oil stone would be the best but, most expensive, choice. So, the process of choosing the correct whetstone for any given purpose is to first determine how fast you would like for the stone to cut and how fine an edge you need, and then choose either a soft, coarse, stone or, a hard, fine, stone of the appropriate type and grit.
this is the first stone I bought. The price is right. Though it wears really quick. I would say buy a king brand stone. They are a little more but will last so much longer. The other problem is the stone wears at a strange angle which makes you constantly fix it. Also with the rust remover glued to the side if you don't remove it before fixing the stone will be slanted. Buy a king.
Sharpening kit: Sharpening kits appear at the top end of the market for knife sharpeners, as they have multiple parts to ensure a proper result. The kit allows you to set the sharpening angle you want to use, while working from course to fine sharpening. Sharpening kits work great for both sharpening and honing. Using a sharpening kit properly requires some time invested in learning to use the kit. However, for those who demand a perfect blade, the sharpening kit achieves the desired result with full manual control.

Both Belgian Blue and Vielsalm Coticule are ancient stone layers found in the Belgian Ardenne Mountains with characteristics similar to both Novaculite and Siliciclastic sedimentary stone in that it is a metamorphic stone consisting of both gray and yellow volcanic ash mixed with tiny Spessartite Garnet crystals suspended in a clay matrix. However, due to its geology, both types of stone occur only in vertical seams sandwiched between two thick layers of bluish-purple slate and thus, they must be meticulously extracted mostly by hand. However, this type of extraction process is both very time-consuming and very labor-intensive and, quarrymen can only extract the stone for a few months each year due to inclement weather conditions. Consequently, both Belgium Blue and Coticule whetstones tend to be somewhat expensive.
